Add support for afterscriptexecute for better Ublock Origin working
Script tag filters do not work in Chromium-based browser. It is chromium bug 168175. It need for blocking inline scripts.
We have to wait until Chromium devs have fixed this issue.
I guess, the Vivaldi dev team has not enough spare time to backport such fix to Chromium.
4 years gone. Google is advertising company and imho they do not need this. It may be one more special capacity that distinguishing Vivaldi-browser from other chromium-like.
